For the past few years my wife and I have seen many doctor's offices and medical centers...more than we can count. But we go there to get advice for healing, comfort from pain, new technologies, tests, etc. Yes, we are practicing medicine with the rest of those who are professional practioners. The doctors, physicians, nurses, technicians, and receptionists at these facilities that we go to have become friends. But we know deep down, they only have answers to historical data and not necessarily answers to the current situation.
Just a couple of weeks ago, we ended up in an Emergency Room and had to explain our situation. The nurse that was initially helping us asked us what was going on and so I repsonded and the nurse said, "Stop, you've said more than I know anything about. Let me get the doctor."
Is that what worship is about, practicing medicine? Those attending come for healing, comfort, freedom from pain/sin, and to rejoice in healing. We eagerly await for those leading worship to say, "Stop, let me get the doctor/physician". In this instance it would be Jesus Christ--Our Great Physician. Only this phyisican isn't practicing - he's the professional and has done the research, has come to the operating room, and has ran all the tests we need. He has given us a dose of medicine (Balm) to heal our "sin sick soul".
I'm not saying that we as worship leaders are the gate to Jesus Christ, but we allow those in attendance to see Jesus for who he is and what he has done. He has gone to medical school, practiced the techniques and has perfected the outcomes of our soul, and our life.
Let's not forget that in all of our work in preparing for worship on Sunday, regardless of the genre, that there are people in attendance who need healing and a "balm" to sooth the sin sick soul that we all have in our week-in, week-out, lifestyle.
